Looking for some educated guesses. My daughters hatched these two babies in an incubator on March 21st so they are three weeks and a day. They both hatched within hours of each other. One is very feathered and has a long tail (Buttercup), the other is much fluffier and a little heavier bodied (Peepers). Is the feathered one a girl and the fluffy one a roo???? Our experience with chickens is exactly three weeks and a day so some help from the old timers would be greatly appreciated!!!!!
